Abstract

The various operating parameters of this implantable digital pacemaker can be set from outside by means of control signals. The control signals received by a receiver, e.g. magnetic tongue switch, are processed by a pulse generator (151) to form a digital signal, and the latter is processed in a counting device (182) to form a binary signal which denotes the number of the pulses present in the control signal. The binary control signal is not input by the counting device (182) into a memory (184) until the complete control signal has been received by the receiver. The controlling equipment, such as frequency regulator, amplitude regulator, pulse width controller, etc. is connected to the memory (184). Intermediate storage of the control signal in the counting device (182) excludes faulty adjustments as well as undesired short-term intermediate adjustments. <IMAGE>
